Rate lock used in a refinance transaction to hold quoted mortgage pricing for a defined period.
A refinance rate lock is a rate lock used in a refinance transaction to hold quoted mortgage pricing for a defined period.
Refinance rate lock matters because refinance timing can stretch across payoff ordering, appraisal review, title work, rescission timing, and closing. If market pricing changes before the lock is in place, the refinance economics can change.
The term also matters because a lock is not the same as loan approval. It protects a pricing commitment under stated conditions, while the borrower and property still have to clear the rest of the refinance process.
Borrowers encounter refinance rate lock after choosing a refinance option and before the transaction closes.
The term becomes practical when comparing whether the expected savings, Break-Even Point, or Recoupment Period still make sense under the locked pricing.
| Term | Main point |
|---|---|
| Rate Lock | Broad lender promise to hold pricing under stated terms |
| Refinance rate lock | Rate lock applied to a refinance transaction |
| Lock Period | Time window for the lock |
| Rate Lock Extension | Extension if the refinance does not close before the lock expires |
A borrower refinancing to lower the payment locks the rate for a defined period. If the refinance closes inside that lock period and conditions are met, the borrower receives the locked pricing rather than later market pricing.
Refinance rate lock differs from Rate Lock because rate lock is the broad pricing term, while refinance rate lock applies that concept to a refinance transaction.
It also differs from Refinance Closing Costs. Closing costs are transaction charges, while the lock controls the rate and pricing commitment.
